Can the self-regulating Cozy Heat cable be used for slab heating?

Yes. The self-regulating variant can be used for slab heating applications — adhered to the underside of the concrete slab using aluminum tape and fasteners, as with the MI variant. The SR variant’s self-regulating characteristics mean it will reduce output as the slab reaches temperature, providing built-in energy efficiency without requiring a separate thermostat to manage overheating. For higher heat loss requirements where maximum output is needed consistently, the MI variant is the recommended choice.
